EV Owners Shun ICE Loaners



Hopefully more dealers will understand that their EV customers want an EV loaner when their car is in for service and add them to their loaner fleet.
I've been lucky enough to own some nice cars in my life. Like most people, bringing my car in for service was never something I looked forward to. However one thing that I did like was when I got an interesting car as the service loaner. I remember one time when my Mercedes ML430 was being worked on I got a black E430 4matic and I liked it so much I almost told the dealer to keep my car and trade it for the loaner.

Today, many dealers have only a small fleet of in-house loaners and use rental car agencies for the overflow of cars that they need. They do it to save money, and I'm sure it does, but they do miss out on the opportunity to show off the other cars that they sell. I still don't fully understand why a BMW dealer for instance would want to put their customer in a car from another brand while they are getting service, it just seems wrong.
I tried plugging in the 135i loaner I had a when my ActiveE was being serviced. That didn't work too well.
However dealers that are beginning to sell electric cars are now finding they have another problem to deal with. Their EV customers don't want to drive a gas car while their car is in for service, regardless of the make or model. I wrote a blog post about this over two years ago when I was driving my ActiveE and now that the i3 has launched I'm watching many i3 owners say the same thing.  One person recently posted this in the i3 Facebook group:

"Most people would love to drive a new BMW 3-Series for a few days as a loaner. Not me. It vibrates, burns gas, I have to use the brake pedal, makes noise and is slow. All this found during the 2.1 mile drive home. Very much so ‪#‎firstworldproblems‬. Think I'm going to bribe my wife for a ride to and from work."

A 2014 BMW 328i loaner? No thanks.
 Imagine that. The BMW 3-Series is considered one of the best cars on the road. In fact, it has was recently awarded Car & Drivers coveted "Ten Best Cars" distinction for the 23rd consecutive year. One would think just about anyone would love to have a new one for a few days while their car was in for service. That's not so if your car is an i3. After driving an electric car for a while, ICE vehicles seem antiquated. You feel the engine vibrations right up through the steering wheel, you hear the engine noise when you accelerate, gear shifts feel clunky and jerky. Yep, once you get back in an ICE vehicle after driving electric you realize what you've left behind and you don't miss it. You've evolved now, and you don't want to go back to the dark ages of the ICE.

Some BMW dealers have already realized this and are including i3 loaners into their in house fleet. This is a great idea for a couple of reasons. First, they can keep their i3 customers happy while their car is in for service, and secondly they can expose some of their other clients to the electric driving experience. Any electric car owner can tell you, getting people to try electric drive is the hardest part. Once they experience the smooth linear acceleration, the quiet vibration-less cabin and the excitement of the instant torque of an electric motor they too will be thinking about going electric. I'm happy to report my dealer (JMK BMW in Springfield, NJ) - perhaps with the help of some encouragement from me ;)  has decided to include an i3 to their stable of loaners. I think this is a great move and will pay dividends for them in the long run.

Like your Model S loaner? Just keep it!
However this certainly isn't just a BMW issue. I've seen Nissan LEAF and Chevy Volt owners lament the fact that they get an ICE loaner car and wish they had an electric option available. Tesla only sells electric cars so they only have electric loaners. In fact, not only do you get a Tesla loaner, but all Tesla loaners are the top of the line P85 Model S. Plus, if you really like the loaner, Tesla allows you to keep it. Of course you have to pay the difference in your car's value and the P85 loaners that you want, but it's a simple process where you just tell them your keeping that car and they tell you how much you owe them for the difference. That's another example of how Tesla is bringing new ideas and improved customer service to the industry.

I am sure that the savvy dealers who provide electric loaners for their EV customers will definitely benefit. The electric vehicle community is pretty close-knit and does communicate amongst themselves. It doesn't take long for a specific dealer to be labeled a "bad" dealer for not being very "EV friendly". Conversely, the dealers who have provided good service to their EV customers have benefited from a high number of referrals. The dealers who train their staff to understand these new cars, provide free on-site charging, and offer electric loaners are the ones who are really going to succeed in the new electric frontier.

Born Electric Guest Blogger: Meet Scott From California




Hi, my name is Scott Lawson and I was Born Electric on August 11, 2014.

I confess: I am not a ‘car guy’. For me, cars are dirty explosion factories full of toxic liquids and endless grime. Oil changes, frequent fill ups, dusty air filters, and a noisy engine seemed to be an unnecessary evil. If I was to get an EV, I wanted it to be 100% electric, no engine, no gas, no oil, no going back! At times, I have even thought that if I lived in the city I would outsource my transportation to taxis, buses, and trains. But living in the so-called mega-city of SoCal (from San Diego to Santa Barbara) with inadequate public transportation options, a car is required. And since I am confessing, I should say I love traveling fast and zipping around in a driver’s car. Over the years BMWs have fit my needs well but were still powered by gas. I considered the LEAF for a fleeting moment and the Tesla Model S seemed like a car for executives or super models! And costs twice as much as any car I have ever owned.

My i3 in the mountains
BMW decided several years ago to create the BMW “i” sub brand and delve into creating a new kind of transport which they call ‘sustainable mobility’. More than just making an electric car, BMW is looking to change how personal transportation is defined. When the i3 hit the market I was excited to learn more; and the more I learned, the more I felt one with the design principles and philosophy. I am a system architect and strive to make technology useful to people and efficient for business. As I discovered more about the BMW i project and their first product, the all electric i3, I appreciated the innovative use of technology both in the machine and for the consumer.

At the San Antonio dam
The i3 driving machine’s body is made of carbon fiber reinforced plastic (CFRP) including fibers from the Kenaf plant (Hibiscus cannabinus), a form of hemp, for the interior. The manufacturing of the car is computer-controlled and ultra clean using robots, clean rooms, heat-activated glue welds, an all aluminum body, and powered by wind and hydroelectric power. As I read how BMW designed the car as ‘electric first’, I appreciated the lack of a large front hood, the use of tall skinny tires for less rolling resistance, that the ultra-light CFRP and aluminum construction allowed more efficient range. The opposing doors are possible because of the structural integrity of the material and the short overhangs on the front and rear help parking the car in a busy city. All of this adds us to a futuristic design not only in looks but in function. All of the thought that was put into the sustainability and design impressed me even before the first torque-filled test drive.


As an explorer of new technology I was impressed with the consumer technology built into the car. Integrated sensors and computers help in safety and convenience from the door locks to the theft protection to active cruise control to the integration with internet applications. The maps not only have traffic, but charging stations, mass transit stations and other points of interest. The i3 can listen to you with voice commands and read news and social media updates. The iDrive controller even has one-finger handwriting recognition so you can spell destinations or peoples names. The 20 GB music storage is fast and you can even play video from a directly connected USB drive (while parked, of course!). All of this adds up to the i3 being more than just the ultimate driving machine and turns it into the ultimate transportation machine. I feel it can transport me in time by delivering information to keep me efficiently connected to my social circle and work activities.
Up at Mt. Baldy
This is a new way of thinking. Just as cloud computing and mobile have changed the way we think about file storage, applications, installing software, and upgrades, the i3 alters the way we think about driving. It is something you have to not only experience, but something you have to work with and adapt to. It is a new way of driving. The “one pedal” experience is awkward at first, almost annoying, until you get the feel of it and think about electric propulsion. Driving one pedal is the best way to accelerate and decelerate and you begin to think about gliding to a stop and working with the force of the car. Your right foot is always active but never leaves the main accelerator pedal.

You have to change your thinking about “fuel” and trip planning. You can charge in your garage with a ‘level 2’ 240v charging station. While it relieves you of having to get gas, you do have to remember to plug the car in when you get home. This behavior is becoming familiar as many, if not all, i3 owners will have some form of mobile phone or mobile device that they plug in everyday. When it comes to trip planning, that requires a deeper shift in thinking. With an EV you just cannot ignore this aspect. Most technological shifts require new modes: you have to plan to record your show if you want to watch without commercials, you have to sync your laptop files if you want to work on them while on a flight, you have to schedule a PC virus check at night to avoid malware. Going on a trip up a mountain in the i3, you need to plan to see if there are charging stations, what kind they are (to make sure you are able to charge on them), and to figure the most efficient path there. The i3 itself helps with this by warning you on your state of charge (SOC) and showing you charging locations near you. But with only 25 miles of range to every 1 hour of charge, this is a slow process. More ‘level 3’ charging stations (also called DC Fast Charge) are coming and the i3 can be configured to use them to get charged up in 20-30 minutes. Unfortunately only in some places in the world today have a large enough concentration of DCFC stations to make longer trip travel carefree.
Cooling off in the shade for a bit
To get the most out of the i3, subtle shifts in thinking make all the difference. To save your potential range you can pre-condition the cabin for comfort while it is plugged in. To save on electricity you can set it to charge when your electricity rate is low. To more easily find your destination you can search online at your desk and send the address to the car via the internet. How you navigate these subtle shifts in thinking is the key to success in the modern EV world.

The i3 has taught me that driving an EV is not just changing how your vehicle is powered. It requires that you accept a new type of mobility and adjust how you approach your car. Many people will say an internet news site is just an electronic newspaper or that Google is just an electronic yellow pages, or that cloud file storage is just a “hard drive in the sky”. All of these ways of thinking miss the point that new paradigms like the i3 are a leap into something new. James May of Top Gear recently wrote this about the i3: “Being a car is just one of its apps”. A famous petrolhead, he sees the paradigm shift, too. You have to challenge yourself and think different. And owning an i3 will help you do just that.


I'd like to thank Scott for sharing his i3 story here. One last thing I'd like to point out is that Scott created a BMW i3 Owners map. You can enter your location and add yourself to the map HERE.  I'm going to do a dedicated post on this soon though because it was a great idea and something I think other i3 owners will enjoy. 

Scott is the tenth Born Electric guest blogger I've featured here and I appreciate the time everyone has spent to tell the readers about their i3 experience. Previous Born Electric posts can be found below:

After 2,000 Miles: The Likes




Now that I've had my i3 for nearly a month, I'm starting to get a good feel for what I like and what I don't. My initial thought was to do one post with both the likes and dislikes at this point, but after assembling the lists, I realized I wouldn't be able to spend enough time on each topic if I did it that way. Therefore I decided I'd do two consecutive posts, with one for the likes and one for the dislikes. I'm tackling the easy one first, the likes:


Adaptive Cruise Control With Stop & Go: This feature is really useful. It's kind of like locking in on the vehicle in front of you with a tractor beam and letting it pull you along. I've found it great for both low speed and high speed driving and the car will even come to a complete stop and accelerate again once the car in front of you does. The only things that aren't perfect is I've found it sometimes leaves too large of a gap in between you and the car you are chasing (for safety reasons I guess) but that allows people to easily cut in front of you if they want to. Also, some times it disengages for no apparent reason and when it does that, the car goes into full regenerative braking mode, since you don't have your foot on the accelerator. It seems to do it more in the rain and also when approaching overpasses. Both could possible confuse the camera-based system. That is not an ideal situation by any means, and something I hope BMW will address with a software update in the future. If the adaptive cruise control does disengage by itself, the car should temporally suspend the regenerative braking until the driver touches either the brake or the accelerator themselves. 
This display appears when the adaptive cruise control system automatically disengages

Seating Position: Like many things in any "likes & dislikes" list, this is highly subjective. The seating position in the i3 is very high, and really "un-sports car like". It's actually like sitting in a mini SUV. I like this position and really like the outward vision you get in the car, with lots of glass surfaces and an absolutely huge windshield. The only thing I had to get used to was that you cannot see the nose of the car at all. The hood drops off so prominently, it's impossible to see it from inside the car. After a week or two I was past that though, and feel totally comfortable with not being able to see the nose at all.
The high seating position and the abundance of glass allow for a great outward view

Charging Rate: One of the advantages of having a small battery in your electric vehicle is that it will charge quickly, provided it has a robust onboard charger. The i3 is supposed to be able to accept up to 32 amps @240V which would be about 7.7kW. I haven't seen my charge rate quite that high, but I do seem to be pulling about 6.9kW from my home EVSE. That's good enough to refill a fully discharged battery in about 3.5 hours, or give me roughly 25 miles of range per hour of charging. My ActiveE took about 5 hours to fully charge when it was new, and then when BMW lowered the charge rate due to onboard charger problems, it was taking nearly 7 hours to fully charge. My i3 charges in about half the time it was taking my ActiveE and that makes such a difference for someone like me that does a lot of driving.
Charging at home. The quick charge rate has allowed me to drive 120+ electric miles in the same day without the need of the REx a couple times already.

Cargo Space: For the past five years I've been driving BMW's beta test electric vehicles which were converted gas cars. Both vehicles had severely compromised cargo areas because they were conversions. I use my car to run errands for my restaurant and I'm frequently picking up various supplies. The hatchback cargo area of the i3, especially with the seats down is so much more useful than either the MINI-E or the ActiveE was and I'm so happy to finally have a real purpose built electric vehicle. The battery packaging doesn't interfere with any of the passenger or cargo space, as it's located directly beneath the passenger compartment in one large aluminum case. As much as I liked my previous EV's, the fact that they were indeed conversions did limit their utility.

The Interior: If the unconventional exterior styling has some people scratching their heads, just tell them to open the doors and take a seat inside. The interior is stunningly beautiful, with well laid out instruments and more space than a car of this size ever deserves to have. The tall body and wide stance allows the i3, which is more than a foot smaller than a 1-Series to have nearly as much interior space as a 3-Series. The huge 8.8" center instrumentation screen is amazingly clear, and somehow doesn't have a glare problem as I feared it may. The seats are comfortable and the armrest is adjustable so you can set it at the height you prefer. There is plenty of space to store stuff with huge door pockets, each that will hold two beverage bottles. There are two cup holders between the rear seats and two cup holders in the front with a slot for another optional cup holder. In all the car has up to nine beverage holders. I thought German engineers didn't understand the American obsession to hold drinks in the car?

The Efficiency: The i3 is the most efficient passenger car available in the US. So far, according to the data I'm compiling it's nearly 25% more efficient than my ActiveE was. That means I'm using 25% less energy that the ActiveE which was a pretty efficient EV in its own right. I actually did a blog post last week on the subject of efficiency which you can view here.
If you can curb your enthusiasm for the instant torque, the i3 can be an extremely efficient machine

Comfort Access: OK, so this isn't really anything related to it being an electric vehicle, but it's the first car I've owned with this feature. You just walk up to the car with the key in the pocket and it unlocks when you grab the handle. Then get inside and just press the start button and it turns on. When you leave you just touch the door handle in a particular spot and it locks. The only thing I don't like about this, which will definitely be mentioned in my "dislikes" post, is the extremely loud beep the car makes when you lock or unlock the doors. It's ear-piercingly loud and makes everyone in the general vicinity look your way. Update: It was pointed out to me in the BMW i3 Facebook group that you can disable the beep which I just did. For those wanting to do the same, it's in Settings>Doors/Key>Acuoustic sig.Lock/Unlock. I believe the base model (Mega World in the US) doesn't have the beep feature, but Giga and Tera Worlds do, and you can disable it there.

The Range Extender: I was on the fence for a long time trying to decide whether to get the REx or not. Once it became evident the BEV i3 wouldn't have a real 100 mile range that I could depend on, the REx really became a necessary decision. I'd prefer having a 100 mile EV and a good robust fast charge network, but that will take a few more years, at least here in the North East. For now, the range extender concept works perfectly for me. When I first got the car I purposely didn't charge it so I could fully test the REx performance and it worked even better than I imagined. I did about two hundred miles of driving in REx mode, mostly highway driving at 70 to 75 mph and it was perfectly capable of maintaining the charge. I still haven't had time to really test it by overworking it until it cannot sustain the charge, but I will. The good news is that I'll have to actually try to do that, because it is definitely robust enough to do anything I'll need it to, and that includes 230 mile trips to Vermont. I drive about 30,000 miles per year, and I'm guessing I'll do about 1,000 miles with the REx running. The one great thing about the REx is not having to think about where I'm going in order to make sure I can plug in if I need to drive a little farther than planned. I believe in the near future the range extender won't be necessary, but with where battery tech and charging infrastructure is today, I believe it makes sense for a lot of people and will certainly help with the adoption of electric vehicles.
The i3's range extender sits next to the electric motor above the rear axle.

Collision Warning: Collision Warning with Brake Priming Function is activated at speeds up to 35 mph. It  is able to respond to both moving and stationary vehicles ahead, as well as to pedestrians. If you are rapidly approaching a vehicle or pedestrian, it offers a audible warning and "primes" the brakes so they are ready for the moment you depress the brake pedal. BMW claims this allows for shorter stopping distances. What I really like though is the audible alert. I've only had it come on twice so far and in neither time did it actually prevent me from having a collision, but I could definitely see it doing just that under certain circumstances (like distracted driving). It's definitely a neat safety device and one that I hope all cars have some day.

Hill Hold: If the BMW engineers that are responsible for the hill hold on the i3 are reading this I'd like to say something: Bravo! You nailed it! Electric cars will roll freely forwards or backwards like manual transmission cars do. For the ActiveE, BMW employed the same kind of hill hold feature like they do on their conventionally-powered cars. You needed to depress the brake pedal to activate the hill hold feature, and it would release in a couple seconds. It wasn't bad, but it wasn't perfect either. The i3 won't roll backwards at all unless you put it in reverse, and you don't need to depress the brake pedal to activate the hill hold, it just does it automatically. However it will roll forward to assist in your launch, which is the way it should be. The hill hold feature doesn't time-out, and holds the vehicle as long as you need it to. This seems so natural when you drive it, and now that I've experienced it I'm wondering why no other electric vehicle manufacturer has come up with this yet. I'm sure they will copy it though.

Soft Speed Limiter: This is another feature that I believe is unique to the i3 and is pretty innovative. Perhaps the biggest range thief with electric vehicles is excessive speed. The i3 employes a unique soft speed limiter to gently remind you that you are driving fast and perhaps you should consider slowing down to extend your range. There are three driving modes in the i3: Comfort (this is what the car defaults to) Eco Pro and Eco Pro +. There is no soft speed limit in Comfort mode, but while driving in Eco Pro and Eco Pro +, the soft speed limits are at 75mph and 55mph respectively. The reasoning behind this is if you are in comfort mode, you likely have plenty of range and aren't consciously concerned with extending it. However if you selected Eco Pro or Eco Pro +, you likely are concerned with how much range you have and are making an effort to maximize it. Since driving fast is very inefficient, the car coaches you a bit and "reminds" you that you may want to slow down. Here's how it works: When you reach the speed that the soft limit is set at (75 mph  for Eco Pro and 55 mph for Eco Pro +) the car will not exceed that speed, even if you continue to depress the accelerator. In order to go faster, you need to continue to depress the accelerator further and after a couple seconds it realized that you are aware that you're passing the soft limit but wish to do so anyway, and it will indeed accelerate. It actually takes off rather quickly with an abrupt burst of speed at that point, almost as if to say "Well you asked for it!" I really like this "coaching" feature. There have been plenty of times in my other EVs that I was driving on the highway and wanted to keep my speed down a bit to conserve energy but would find myself creeping up and driving faster than I wanted to without noticing it. With this feature, you really won't pass the soft limit without really intending to, you can't do it by accident.
When you activate Eco Pro +  mode, you get this display prompting you to keep your speed under 55 mph for maximum range. This lead some people to assume it meant the car wouldn't go faster than 55 mph in this mode, which is not correct.

Acceleration: I saved the best for last. The i3 is really a blast to drive. I have the REx i3 which is about a half a second slower than the BEV and have been timing myself from 0-60 in around 7.6 seconds. It's not Tesla fast, but it is a really a quick little car and is much faster and more fun to drive than my ActiveE was. The instant power in the 10 mph to 50 mph range is amazing and feels quicker than my Porsche Boxster did when accelerating at those speeds. This is indeed a fun car to drive, and drives so much better than anyone would expect just from looking at it.

BMW i3 Delivery Tips



Did you know your i3 has a little tab to hold the charge port cover while it's charging? Bet you didn't!
Over at our Facebook i3 group we have complied a list of a few "Getting to know your i3" facts. I've put them together here to give new i3 owners a quick run-down of some of the things you may not find in the owners manual or be told by your dealer. The electric vehicle community has proven to be an invaluable resource for new LEAF, Volt and Tesla owners and I expect the same to happen with the i3. There is so much new ground to cover that the dealers simply can't provide all the information the customers need. That being said, they need to do better than what we have seen so far. If you have more tips and suggestions, please leave them in the comments section below and I may even add it to the post.
  • Your car is delivered with both charge rates purposely set to low. If you took delivery and are wondering why it's taking much longer to charge than you expected, this is the reason why. You need to go into the idrive settings > Charging and adjust to maximum setting.  Be aware that you can set these yourself and you might need lower settings depending on available current when charging.
  • Both seats will be likely be set up to the maximum height. Pull the lever to go down so your wrist can rest on the pad by the iDrive. The height of the armrest is also adjustable. Pull the tab on the leading edge up and you can set the height to your liking. The steering column not only adjusts up and down, but it also telescopes outward and is adjusted by the lever underneath the steering column.
  • Be mindful of the speed restriction setting in ECOPRO (75mph) and ECOPRO+ (55mph). You may need to adjust it. The car doesn't actually have a hard speed limit at those marks, but when you reach those speeds it temporarily holds the car from accelerating past them. If you want to go faster you really need to push the accelerator further to bypass the "soft" speed restriction. It is more of a gentle reminder to watch your speed than an actual speed limit.
  • The rear passengers can let themselves out by pulling the front seat headrest cable and pushing the seat forward to reach the door pull. 
  • To lay the rear seats flat, there is a fabric loop that you pull on the bottom corner of the seat back.
  • The front trunk is not water tight and under certain conditions water may spray up into it so don't put anything in there that can be ruined it if gets wet. If you need to do so, buy a watertight bag to store it in. Many people will keep their 120V occasional use EVSE up there. While it is indeed fine for outdoor use, I'd recommend storing it in a waterproof bag up there also so water doesn't pool up in the connector frequently.
  • There is an extra drink holder under the arm rest that you can insert at the front of the center console.You can also purchase an additional one and have three cup holders in the center console.
  • Check to make sure the AC and charging system is working before you leave the dealer; BMW disables both for shipping and the port or dealer needs to enable it before delivery. There were quite a few people in Europe that had this issue and now a few in the US are reporting  it also. It is evidently a 15 minute fix to enable the A/C at the dealer, provided your dealer has been trained on this and knows how to do it. Unfortunately not all dealers know this yet!
  • Download the BMW i Remote app from the iTunes store and have your CA register you for it.  More detail: There are two BMW apps , MY BMW Remote app and BMW Connected app. Which is correct?BMW i remote and BMW Connected (both for US) are correct. My BMW Remote was used for the ActiveE and is no longer applicable. Is the BMW Connected app used to monitor charging, precondition etc.. or is that a different app? The i Remote is for pre con and opening the doors etc. The Connected one does have some monitoring but it's mostly to run apps in the car (via a standard USB-to-phone cable rather than bluetooth) Go to iTunes App Store, put in search string “BMW” in search box, Filter for iPhone Apps only. (See photo of resulting apps, loaded as a separate file under the title "BMW iPhone Apps for i3")
  • Ask your insurance company for the Hybrid or Electric Vehicle discount.
  • Press the end of the turn signal stalk on the left side of the steering wheel to display the external temperature on the driver info screen.
  • Press the small button on the left side of the Driver Information Screen to reset the trip odometer displayed on that screen. The other trip computer is reset from within iDrive.
  • To play Pandora in the car, install apps from ConnectedDrive menu in idrive, then plug your phone into the USB cord and launch Pandora. The Pandora icon will appear in the radio menu. You can then use idrive to control Pandora in the center screen.
  • Download the BMW ConnectedDrive App to get many other features and apps like BMW Radio, Audible, Glympse, Amazon Cloud Player, Rhapsody, Stitcher, Aupeo, Facebook, Wiki Local and Twitter. You have to connect the USB cable to make it work.
  • When charging you can use the hook on the charge flap to hold the plastic "gas cap" cover. there is a small slot under the plug cover that aligns with it.  Or you can drape it over the top of the J1772 plug rather than letting it dangle in the wind against the paint.
  • Before you leave the dealership, put the car into reverse with no surrounding obstacles and verify that the sensors all work.
  • If you didn't order your car with the Technology Package, you may be missing the default code 606 navigation package.  BMW acknowledged that they was a problem and some cars didn't have the basic navigation installed:     

    "Today, we have identified a number of i3 Rex (Model 14iB) that have not been equipped with the standard Navigation Business system (Option 606). Your dealership has taken delivery of one or more of these vehicles. We are actively investigating and considering all avenues (option retrofit, option credit, vehicle reorder, etc.) for a dealer/consumer friendly resolution. We will have further updates as new information arrive.
    "
 Followed by:

 "We expect to know by Monday, June 2nd, the status of the retrofit for the missing Navigation Business system (option 606). The affected vehicles include all i3 Rex vehicles without ZTD (Technology + Driving Assistant Package) produced weeks 10 through 22 and half of week 23. Any vehicles that arrive at your dealership without Business Navigation can be retailed but you must disclose the missing option to your customer. The remaining affected vehicles will not be released until we have an update."
  • When you get home, press the BMW Assist button on the overhead console (open the button cover to reveal it) and speak with a representative to activate and set up your account. It takes about 5 minutes.
  •  
  • There seems to be some capability issues with the i3 and EVSE's made by Leviton. I know of three people that have reported their i3 won't charge on their Leviton unit. I have personally reported this to BMW engineering and contacted Leviton to help put them together on the issue so hopefully they will figure it out and correct the problem quickly.
  • Send a place to your car:  You can send a place in Google Maps to your car using the Send to Car feature. The first step is to add your car: Go to https://www.google.com/maps/sendtocar. Click Sign in and enter your account information. Click Add car or GPS device. Select “BMW" from the car type dropdown menu. Type in your account ID (email address) provided by your car manufacturer in “Account ID” field. Go to Google maps, look up a business or address and click the More link to send.  Once you send it from your pc google maps to the car you click my messages under bmw connected in the iDrive. Open the message and you will see the checkered flag to initiate navigation.
  • The radio will continue to play for a few minutes after you exit the vehicle. If this bothers you then press the Start/Stop button again with your foot off the brake pedal and it will shut off.
  • Check to make sure the tow bolt is located in the front trunk of the car or elsewhere. Page 195 of the owners manual says the tow fitting is located in the storage compartment under the hood. It should be wedged into the foam caddy for the tire inflation kit.
  • You can set your presets (above the AC 1 thru 8) to different functions to fit your own needs. I did this in the ActiveE, and to simplify the process, hopefully this will make sense.  Go into the idrive and select your sub menu, example click on vehicle info, then choose trip computer.  Don't select trip computer, but turn the idrive controller over it until the check mark shows.  Then select the preset you want, and press and hold until it confirms.  it should then show up on the top of the screen with the rest of the presets in blue.  You can absolutely go into the sub menus and select options to save on some things, but not on others.  Play with it.  I also selected all of my radio/satellite presets and saved the presets as a preset.  When you leave the radio is preset mode, you can then scroll thru the radio presets on the steering wheel while in other menus.  
  • Download the following apps to locate charging stations and set up the associated accounts. It's good to have a few of them as none seem to have all the charging stations available listed: Chargepoint, Greenlots, Plugshare, Recargo, Blink, Carstations.

First i3 REx Road Trip: Hotels, BMW Dealerships & Wraps



Charging up at Hampton Inn in Turnersville... but for how long?
Ever since the i3 colors were announced, I had thought about doing a custom color wrap for my i3. The colors offered just weren't very inspiring and other than the Solar Orange, they were all white and shades of grey or silver. I chose the Laurel Grey because I liked how it made the car look more like one solid color. It minimized the "Black Hand" design that BMW used to try to give the appearance that the i3 is slimmer than it actually is.  It's a short car that is tall, and definitely has unusual lines and BMW believed that using black on the top surfaces would make it look less "chunky".  I also liked the idea of having a custom color so my car would be easily identifiable in pictures. I'll be writing i3 reviews for quite a few websites, and having my car a distinct color will let the readers know immediately that it's my car they are looking at.

Once I got to see my car in person I realized how much I really do like the Laurel Grey
That being said, once I got my car I realized how great the Laurel Grey looks, especially with the Frozen Blue accents and I started having second thoughts about doing the wrap. I decided to go through with it anyway because I really like the idea of having a distinctive color that no other i3 has. Plus, when I take it off it will feel like I got a new car again because the wrap protects the paint perfectly underneath. Since I'm wrapping a new car the paint will remain pristine and in a year or so when I decide to take it off I'll be able to enjoy the Laurel Grey with Frozen Blue color scheme.

After doing some research I decided to get the wrap done at Designer Wraps in Millville, NJ. It's about a 130 mile trip from my house and while there are closer wrap shops, I want to get it done somewhere that has a great reputation and has been doing wraps for a long time and Designer Wraps fit the bill. So I plotted the trip and since the wrap takes 3 or 4 days to complete, I told my wife I'd need her to drive down with me separately so I could drop off the car and we'd drive back together. The funny thing about it is she initially said, "How long will that take? Is there a charging station along the route where you can stop and charge?" She momentarily forgot I have the range extender on the i3 so she was thinking this would be an all day road trip. After driving pure EVs for five years now, she had been conditioned to think a long trip meant 80 miles or so of driving, and then four or five hours of charging in order to continue. After staring at her and smiling for a few seconds, she realized her error and we just laughed. Only two days of ownership in and the REx is immediately a game changer.

Then I realized I had also overlooked something, but not anything with regards to the car though. We were planning on driving down early on the morning of Saturday, May 24th, and that turned out to be the Saturday of Memorial Day weekend. If you live in New Jersey, you know how bad traffic is going south on the Parkway or the Turnpike during either Memorial Day or Labor Day weekends, as tens of thousands of people migrate to the Jersey Shore for these two weekends that bookend the summer. A two and a half hour drive could easily take five hours under these traffic conditions. So we came up with plan B. We would drive about 100 miles late Friday night which would get us passed the major traffic areas, stay in a hotel and continue on the next morning.

Since we would be spending the night, I figured I might as well find a hotel that would let me plug in 120v while we were there. After all, the goal is to drive on electric as much as possible, even with the REx and an overnight stay would give me enough range to make the final 40 miles or so without the REx kicking on. After making some calls, I found an Hampton Inn in Turnersville, NJ that said I could plug in and it was just about perfectly along our planned route.  The hotel was about 100 miles into the trip and we would then be 40 miles from Designer Wraps. An overnight charge would give me just enough to complete the trip the next day without the range extender. If I really wanted to, I could have probably found a hotel that was only halfway there, and tried to complete the entire trip without the REx, but then I would have needed to find a L2 240v EVSE, as overnight charging on 120v wouldn't have been enough to fully replenish an empty battery. It just wasn't worth the trouble, and if everything worked out, the 140 mile trip would end up with me using only a little more than a half a gallon of gas and without any inconvenience.

I drove nearly 90 miles before the REx came on
It was raining heavily for most of the drive there so I wasn't expecting to beat the car's predicted 75 mile electric range but I did. I was shocked when I drove 89 miles, mostly at speeds of 60 to 65 mph but occasionally faster, before the range extender turned on to hold the battery charge for the final 9 miles. There was traffic so we did occasionally drive for a while at about 50 to 55 mph and I did activate Eco Pro mode about halfway into the trip. I didn't really do so to extend my range because driving at constant highway speeds requires a certain amount of energy regardless of what mode you are in and I don't think Eco Pro will really help out much at all with this kind of driving. I really just wanted to see if there was any noticeable difference in the driving behavior and found out something very interesting that I haven't seen reported anywhere before. When driving in Eco Pro mode the car tries to keep you from driving faster than 75 mph. If you are in Eco Pro and accelerating, when you hit 75 mph the car holds at 75 mph momentarily, and in order to go faster you need to really push the accelerator further than you would normally have to in order to continue accelerating. It's kind of like the car is coaching you to not exceed 75 mph because of how inefficient it is to drive at that speed. Once you continue to push the pedal further, it realizes you really do want to go faster and it takes off with a bit of a surge. I then tried this in Eco Pro+ mode and found out it does that same thing at 55 mph in that mode. This is a nice feature to "remind" you that driving faster will consume more energy than you may want to. This only happens in Eco Pro and Eco Pro+, and not in the default Comfort driving mode.

We arrived at the Hampton Inn around 1:00am with 98.1 miles on the trip odometer, and only the last 9 with the range extender in operation. The gas gauge barely moved and looked like I only used about 1/12 of the tank. The gas gauge showed 62 miles of range remaining and if that held true, then I would have had 160 mile range total; 89 on pure electric and 71 on gas.


Plugged in at Hampton Inn
After checking in and confirming it was OK with the front desk attendant I went outside and pulled my car to the front door where there were two brand new 120V outlets, one on each side of the front entrance. I checked around the rest of the building and didn't see any other outlets that were assessable. I'd prefer not to be plugged in right in front and draw attention, but it was the only outlet available and I was able to pull over to the side and well passed the entrance so the car wasn't in anyone's way.  I got up around 7:30am and checked my app to see the state of charge and noticed the SOC was at 30% but that the car was no longer charging and had a "charging error" at 5:07am. I went out to the car and saw it was unplugged from the wall so I plugged it back in and went to the front desk to ask if there was a problem. It was a different person than when we checked in and she told me the owner came in and unplugged the car. I explained to her that I called ahead to ask if I could plug in and was told it wouldn't be a problem and that I told the person the night before that if there was indeed any problem to please call my room. I also asked if I could speak to the owner was was told no, I could not. With that I told her that I plugged the car back in and if the owner has a problem with it to please call my room as I would like to discuss this with them.

After about 15 minutes my smartphone app notified me that the car had another charging error so I went back down to try to straighten out the situation one more time. Again the car was unplugged so I went to the desk to ask to speak to the owner and again was told they are unavailable. So there was nobody that would even address the situation with me. I then very politely informed the person at the desk that I'd be contesting the charge on my credit card and refusing to pay for the one night stay as well as contacting Hampton Inn customer service. Hampton Inn boasts the "100% Hampton Guarantee" that promises "If you are not satisfied, we don't expect you to pay". Honestly, if someone would have just talked to me and given me any reason, even if it wasn't a valid reason like "Due to insurance concerns we can't let you charge" or "Other guests were complaining that you are getting free fuel but they aren't" I would have accepted it and agreed to pay my bill. While I wouldn't be happy and would likely write to Hampton Inn asking them to consider changing policy, I wouldn't have evoked the Hampton Guarantee and told them I will be writing customer service and asking to be refunded. The fact that nobody there had the decency to even talk to me about it, or call my room to explain that they needed to unplug my car tells me they don't care about offering acceptable hospitality. If you don't fit into the box of what services they expect to provide for their typical guest, then you are out of luck and they won't even discuss the issue with you, and that's very unfortunate. I understand this is new territory for many hotels, and that I shouldn't feel entitled to charge my car wherever I want to. However I did ask first and I did make it clear that if there was a problem to please call my room to discuss it with me. I would never lose my temper or get confrontational with anyone in this kind of situation. I believe the early adopters need to be ambassadors for plug in cars, paving the way for the rest and we need to do our best to educate the uninformed as to why this is indeed a better path for us all. I will certainly be in touch with Hampton Inn's customer service this week, and try to encourage them to proactively adopt a charging-friendly policy for all of their locations. So perhaps something good will come us this unfortunate incident.
Will Hampton Inn honor their guarantee? I'll find out soon
Charging at Camden County College
Realizing I didn't have enough charge to make the final 40 miles to Designer Wraps, I pulled out my phone and looked up the charging stations in the area. I found that Camden Community College was only a few miles away and they had two level 2 EVSEs. So we headed over there, found the two Blink stations, plugged in and went out for a bite to eat. After breakfast we went back to the hotel, got our belongings and went to check out. By then there was a new person at the desk and when they asked if everything during our stay was OK I told them it wasn't and explained the charging issue. She seemed a bit confused about what to do but didn't offer any help or even to get a manager so I just thanked her and informed her that we'd be contacting Hampton's customer service to take up the issue with them.

Giving a quick i3 seminar!
We headed back to get my car and when we arrived we were greeted by a security guard who was checking it out. He loved it and wanted to know all about it. After giving him the basic i3 101 lesson, we were off to complete the mission. By this time I was about 60% charged and had plenty of juice to complete the final 42 miles. The whole trip was 140 miles and I finished with a consumption rate of 4.2 mi/kWh. I dropped the car off, was told it will be ready by next weekend and headed home. I know I've only had the car three days, but I've driven it nearly 400 miles already and have loved every mile. I'm really glad I decided to get the range extender, it makes the car immensely more versatile, especially for high mileage drivers like me. I know I only needed to use it for 9 miles out of this 140 mile journey, but just knowing it's there in case I do need it will allow me to take trips I normally wouldn't have with it.
Final stats of the trip
There is one more note to make about the trip. Knowing that I would be very close to a BMW dealership while we stayed at the hotel, I contacted BMW of Turnersville the day before to see if I could plug in to their EVSE overnight so I'd be fully charged the next morning. The receptionist answered the phone and I then said this to her: "Hello. I'm going to ask you a question that I bet nobody has ever asked you before, but I promise you that will will hear it a lot in the coming months and years".  She laughed a bit and I then told her I was driving my electric BMW i3 to the area from Northern NJ and I needed to charge it. I wanted to know if I could plug into the charger at their dealership. She replied that I was correct, and nobody had ever asked her that and that she'll have to ask someone about this. She put me on hold for awhile and then another person picked up from the service department. They had no idea what I was talking about. Even after explaining that I just bought a brand new BMW i3 and that it was electric, they had no clue about the car or if they had the means to charge it there. I assume if the dealership had a charging station the service department would likely know about it, so just as I was about to say thanks anyway and hang up the person said they would transfer me to a manager. So on hold again for awhile and then the phone rang and was picked up by a voice mail system that said they were not available and to leave a message. Since I already confirmed that I could plug in at the hotel, I just hung up at that point. This is really inexcusable as far as I'm concerned. I know the i3 is a new vehicle and perhaps this particular dealership didn't even get on in stock yet, but BMW has known for four years now that these cars would be in showrooms by mid 2014. How is it that the people at this dealership weren't prepared to even answer a simply question about charging? It was as if I was speaking a different language. There's a lot of work to do folks.

NYC Infrastructure Hearing



The ChargePoint map of charger locations in NYC
This isn't an i3-specific post, however it is very important to the i3 and to all other plug in vehicles. The city of New York is considering legislation that would help to dramatically increase the number of public charging stations within city limits. While New York has been steadily adding charging stations in private garages and parking lots, there are currently only about 140 chargers in the entire city, and many locations account for multiple chargers so there really isn't a good spread of places to charge in New York City.

Answering questions from the Board
I was asked by Mayor Bloomberg's Office of Long Term Planning and Sustainability to testify in favor of  Intro.1176. There were a few other industry experts that testified and for the most part it seems the Joint Housing and Transportation Board that would be considering the bill was definitely in favor of it. In fact, the Co-Chairman James Vacca actually called for the bill to be expanded to include curbside charging stations which the bill in its current form didn't include.

Intro. 1176, loosely called the "Charger Ready Bill" would require all new construction projects in NYC that are adding 4 or more new parking spaces to install the conduit and make sure the site has the proper electrical capacity for future electric vehicle charging equipment to be installed in up to 20% of the parking spaces added. This is a great bill because it isn't financially onerous on the owner, as it doesn't require them to install the EVSE's or even pull the wiring just yet, but have the electric raceways there for future use. It is not expensive at all to do this while you are building out the parking lot, but it becomes very expensive if you want to do it later as you often have to rip up the parking lot and trench to run the wiring. Having the parking lots and garages ready for future charging equipment will certainly lead to increased charge points as it will be quicker, less expensive and much easier to install them once the owner feels there is the need to.

Unfortunately right now New York just isn't ready for electric vehicles. I go into the City frequently and it's very difficult to get a charger that is available, near the destination I'm going to, working, and not blocked by a row of gas cars. I even did a blog post about the difficulty I had with my ActiveE once last year. Most of the time I go in there now I take my gas car because I can't be sure I'll be able to charge while I'm there and that's unfortunate for me and for the city. Instead of me driving my zero emission car there, I'm contributing to the air pollution problem that every major city has by driving my gas burning vehicle. I even have had people that live in the city email me to ask for advice about getting EV charging equipment installed where they live. It's very difficult to own an electric car if you live in the city because it's so difficult to get it charged without paying extraordinarily high installation fees well into the thousands of dollars.  Hopefully Intro.1176 will pass and we can begin to get the hundreds and even thousands of charging stations that NYC needs to accommodate the wave of plug in cars that will be on the streets of NY in the near future.

How Long Will it Take To Charge an i3?



The i3 will charge in about 3 hours on a standard level 2 supply.
Since installing public charging stations at my restaurant in Montclair NJ, I have conversations with EV-interested folks nearly every day. One of the most popular questions they seem to always ask is how long does an electric car take to charge?

I wish I could just give a quick answer, but it's just not that easy. Nearly every EV takes a different amount of time to charge since they have different size batteries and the also have different charging rates. Then you throw in three different levels of charging (120V, 240V & 480V DC quick charge) and there isn't even a single answer for every car. For instance if I said the i3 takes about 3 hours to charge I'd be correct. However I could also say it will charge to 80% in under a half hour (DC QC) as I could say it takes about 15 hours (simple 120V household outlet) to charge and I'd still be correct. So I try to quickly explain the different methods of charging and the fact that every car is different without totally confusing the person or making it sound so complicated that they are are turned off by it all. After all, getting gas may be expensive but let's face it, it's very easy to understand!

The size of the battery, the onboard charger and the supply provided will all work together to determine how long your EV will take to charge. The vast majority of the time most EV owners will charge their car they will do so on a 240V electric supply, so I'll focus on that here. One advantage "little battery" EV's like the i3 have is since they have a small battery, they will charge relatively quickly, provided they have robust onboard charging capabilities. The i3's standard 7.7kW charger will fully charge the battery in under three hours which is pretty good compared to the other EV's on the market. Only Tesla (9.6kW charging standard) and Renault (43kW Chameleon charger) offer an EV with a faster level 2 charging rate than the i3.

Miles Per Hour:

One way to condense the conversation about charging time is to simply say how many miles of range per hour of charging you get. The i3's small battery (18.8kWh usable) combined with its relatively fast onboard charger will allow you to gain about 30 miles of range for every hour you are plugged into a 240v 32 amp supply. This will be something I really welcome. My MINI-E could accept up to 12kW's and I would get about 30 miles per hour of charging. However after a recent BMW software tweak my ActiveE only gets about 15 miles of range per hour and it feels painfully slow, especially when I need to charge to get somewhere. I am
so looking forward to getting back to charging at 30 miles per hour when I get my i3. Being able to charge quickly on a standard level 2 supply is really helpful and once you've been able to do so you don't want to go to a slower charging rate. The car becomes imminently more usable when you can charge it quickly so I'm glad BMW is offering a pretty robust onboard charger. Now of course I wish it was a 9.6kW charger like Tesla uses, but that's just the part of me that is never satisfied speaking. In reality 7.7kW's is fine for a car with a 22kWh battery. It will charge twice as fast as my ActiveE and deliver about the same range, and that will really make the car much more versatile.

DC Quick Charge: Better Than a Bigger Battery



A BMW i3 charges at the first public SAE CCS quick charge station open in the US. 



The first public DC quick charger in the US that uses the SAE-endorsed Combined Charging System (CCS) opened this week in San Diego, CA. It's located at the Fashion Valley Mall and uses a dual connector quick charger called a "Freedom Station" by EVgo.

The i3 will have a DC quick charge option that the customer can elect or pass on. The price has not been set yet but the speculation is it will cost somewhere between $750 and $1,000 extra. Having the option will allow you to recharge the car to 80% in about 20 minutes. This is an incredible advantage to have in an EV, since charging times are really what limit EVs like the i3 from being able to cover hundreds of miles without much inconvenience. Of course you can get an EV with a huge battery like the Tesla Model S which will allow you to drive a couple hundred miles between charges, but to be able to really cover long distances without much inconvenience, DC quick charge (or battery swap ability) is really needed. 

Standards War

SAE & CHAdeMO side by side
Tesla understands the absolute need for quick charging on pure electric vehicles and is rolling out their own network of DC quick chargers they call Superchargers. Since Tesla uses a proprietary connector nobody other than Tesla customers will be able to use their network. Nissan uses a different connector called CHAdeMO (short for CHArge de MOve or charge for moving) which was developed by Tempco (yeah, the power utility that runs the Fukushima nuclear power plant) for quick charging electric vehicles in Japan. When Nissan came out with the LEAF, the SAE hadn't yet endorsed a DC quick charge connector for the US so Nissan had no other option but to use the CHadeMO connector on the LEAF for quick charging, not that they wouldn't have anyway. Then, once the SAE endorsed the CCS connector, BMW, along with Audi, Chrysler, Daimler, Ford, GM, Porsche all agreed to use it on their plug in vehicles, when they eventually make them. I'm not going to go into why one is better than the other, or why some manufacturers chose one over the other here. There are plenty of articles on the internet that discuss this at nauseam; just do a simple search and you'll find them. I will say that I've talked with a few BMW engineers about this and they all basically told me there was no decision to be made. That the SAE CCS system is so technically superior to CHAdeMO, especially for future applications, that they wouldn't have even considered it. 

Personally, I really don't care which "standard" my EV has, as long as there are chargers out there for me to use. I've held both and even plugged both into cars and the SAE is a little lighter and less bulky and you only need a single charge port on the car so I tend to favor it, but honestly, I would be fine using CHAdeMO if there were chargers installed in my area and there aren't. At the i3 premier in July a BMW program manager asked me how much would I be willing to pay for the DC quick charge option. I suspect the price for the US market hadn't been finalized yet. My response was, "That depends" eliciting his curiosity. I followed it up by saying right now I won't pay a penny for a DC quick charge option because there are no chargers within driving distance of my home. However let's say there were a couple here and there in my general area, then I'd pay about $500 for it. And if there were a couple dozen of them in northern New Jersey I'd be willing to pay $1,000 for it. 

 
I know we are many years from having DC quick chargers in accessible, convenient locations like gas stations but I also believe that day will eventually come. The West Coast has a huge head start over the rest of the country and probably has as much as 70% of the Superchargers, ChadeMO and now CCS stations installed in the entire country. Plus, with the recent NRG settlement California will get 200 more DC quick charge stations, most being dual connector (CHAdeMO and CCS) units. Tesla currently has 24 Superchargers installed and an aggressive plan to cover the rest of the US in a few years. Nissan meanwhile has committed to installing hundreds of CHAdeMO stations in the US although they haven't delivered much on that promise yet. Outside of California's NRG settlement the future is unclear how and when we'll get the SAE CCS stations installed. Without any clear plan for the area you live in, I think it would be foolish to pay up to $1,000 for the option if you don't even know if you'll ever be able to use it. I have a friend that bought a LEAF in 2011 here in New Jersey and paid for the CHAdeMO option but nearly three years later he has never been able to use a CHAdeMO station because there are none within his range. 


I had the opportunity to talk with a BMW manager at the i3 premier about DC Quick charge infrastructure and one of the questions I asked was will the BMW i dealerships be required to install a DC quick charge station. I thought that would be a great way to at least begin the roll out of compatible DC quick chargers for the i3 so customers will at least have their local dealerships to fill up quickly at. They could also look for BMW i dealerships along the route of their long trips and since most dealerships are on highways, the locations would probably be good ones. Unfortunately that isn't going to happen. The dealers will not be required to install DC quick charge stations, but they will be "encouraged to." Personally I'd like to see BMW "encourage" them by offering to supply them with the DC charging station for free, as long as they pay to install, maintain it and have it available for use even when the dealership is closed. The dealerships will however be required to install multiple level 2 charging stations though which is a start, but really doesn't help out with longer road trips.

"Quick" Level 2 Charging

Is there such a thing as quick level 2 charging? While level 2 charging (240v) isn't necessarily quick, some cars do charge quicker than others. The Model S is the king (in the US at least) of L2 charging as it can charge at a rate of up to 20kW with optional dual onboard 10kW chargers. However the real L2 charging champ is only available in Europe. The Renault ZOE's onboard "Chameleon charger" can charge at up to 43kWs! On the other end of the spectrum is the Chevy Volt that is restricted to 3.3kW charging. However since the Volt has a much smaller battery than a Model S, it can actually fully charge in about the same time as a Model S can with it's massive 85kWh battery. The i3 will be able to charge at up to 7.4kW, and since it has only a 22kWh battery, it can fully charge in under 3 hours. This delivers a rate of about 30 miles of range per hour when charging from a 240v 30 amp level 2 charging station. That's a good improvement from my ActiveE, which returns only 15-18 miles of charge per hour. BMW is quick to point out how fast the i3's battery can be replenished while charging on L2, and while it is better than any non-Tesla EV here in the US, it still pales compared to the 80 miles of range you can get in 20 minutes on a DC quick charger.

Bigger battery vs DC quick charge 

The i3's 22kWh battery will allow for 80-100 miles or range in every day driving conditions, and up to 125 miles if the more efficient ECO-Pro+ driving mode is selected (Says BMW). So if range is so important, why not just slap a 40kWh battery in there and call it a day? The i3 would get about 200 miles of range and you wouldn't need quick charge, right? Wrong. Tesla uses enormous battery packs and they still realize they need a DC quick charge network to really make their electric cars viable to the broad public. Even with 200 to 300 mile range their customers want to be able to quickly recharge so they can drive long distances. The truth is, no matter how big your battery is and how far you can drive on a single charge, people will always want more range and quick charging. This is way BMW is offering the range extender on the i3. They know that it's going to take years for a comprehensive DC quick charge network to be built out, so until we have a robust infrastructure in place, the range extender will be a very popular option and will allow the owner to drive as far as they need on the few occasions they need to travel long distances. For daily use they won't use any gas, as the ~100 mile range should be more than enough for the vast majority of the time, yet they still have the flexibility of being able to cover hundreds of miles should the need arise. I believe the range extender becomes obsolete once we have adequate quick charge infrastructure in place. In fact, large Tesla-sized batteries won't be necessary either. Why carry the additional weight around and pay for a huge battery pack when you can use one half the size and just charge it quickly when the occasional need arises? The main reason EVs cost more than conventional powered vehicles is the cost of the battery pack. A smaller pack combined with readily available quick charge is clearly the way to go, however getting the infrastructure in place is the 800 lb gorilla in the room. It's not just going to happen without the support of the manufacturers. Tesla and Nissan seem to be doing their part, will BMW and the others that have signed up to use the SAE CCS standard do their part? Only time will tell.
 
The BMW EV infrastructure team was well represented at the grand opening event for the first public CCS quick charging station. Will they continue to be involved in assisting CCS station deployment, or wait by the sideline and watch?
